Abstract: A gaseous fuel supply for an engine at a wellbore can be regulated using a control system. The control system can include a processing device communicatively coupled to one or more sensors to receive a fuel property measurement from the one or more sensors. The fuel property measurement can correspond to a first fuel source of the engine that can be used as the fuel supply for the engine to power an equipment to perform a wellsite operation. Additionally, the processing device can identify a predefined range of the fuel supply that corresponds to a target performance level of the engine. Based on the fuel property measurement, the processing device can determine that the first fuel source is outside of the predefined range. In response, the processing device can provide a second fuel source as the fuel supply. The second fuel source can enable the engine to operate at the target performance level.

Abstract: A gaseous fuel supply to an engine at a wellbore can be monitored using a monitoring system. The monitoring system can include a sensor apparatus having sensors configured to monitor the fuel supply of the engine. The fuel supply can be transported within a fuel supply line of a wellsite. The monitoring system can divert a portion of the fuel supply of the engine from the fuel supply line to a fuel sampling line. The monitoring system can analyze the portion of the fuel supply using the sensor apparatus to determine a fuel property measurement of the fuel supply. Additionally, the monitoring system can determine that the fuel property measurement is outside of a predefined range associated with a target performance level of the engine. In response, the monitoring system can perform a mitigation operation to cause the fuel supply to enable the target performance level of the engine.

Abstract: A reserve fuel system can be used to supplement fuel provided to an engine of wellsite equipment. For example, a fuel supply line can transport gaseous fuel at a wellsite to an engine of an equipment coupled to the fuel supply line. A reserve fuel tank can store gaseous fuel diverted from the fuel supply line. The reserve fuel tank can include a first valve coupling a first end of the reserve fuel tank to the fuel supply line to divert the gaseous fuel and a second valve coupling a second end of the reserve fuel tank to the engine. The second valve can be in a closed position to prevent the stored gaseous fuel from transferring to the engine or an open position to transfer the stored gaseous fuel to the engine. A control system can adjust the second valve based on a pressure of the fuel supply line.

Abstract: The disclosure provides a method and system for extracting carbon dioxide from an exhaust gas. The method includes lowering a temperature of an exhaust gas using a heat exchanger, lowering a concentration of a particulate matter within the lowered temperature exhaust gas, and passing the lowered particulate concentration and lowered temperature exhaust gas through one or more membrane modules to produce a membrane module permeate flow that contains a higher concentration of carbon dioxide compared to a concentration of carbon dioxide in the lowered particulate concentration and lowered temperature exhaust gas. Further, the system includes a heat exchanger fluidly coupled to a particulate filter that is configured to lower a concentration of the particulate matter within the exhaust gas, and one or more membrane modules fluidly coupled to the particulate filter and configured to produce the membrane module permeate flow.
